How Do the Lungs Work? And the lungs are a core component of this vital task. The lungs are part of the respiratory system, and are divided into lobes or sections. The right lung has three lobes and the left lung has two lobes. You can think of each lobe as a balloon: It inflates when you breathe in and deflates when you breathe out. Each lung sits next to the heart. They are safeguarded by a thin tissue called the pleura. Inside the lungs are millions of tiny air sacs called alveoli. These sacs — about 300 million total — are overlapped or interwoven by capillaries, which are fine blood vessels.

How the Lungs and Respiratory System Work You usually don't even notice it, but twelve to twenty times per minute, day after day, you breathe -- thanks to your body's respiratory system. Your lungs expand and contract, supplying life-sustaining oxygen to your body and removing from it, a waste product called carbon dioxide. The Act of Breathing. Breathing starts at the nose and mouth.

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange Video Breathing Out (Exhalation) When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity. As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth. Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity.

How Lungs Work 1 CAPILLARIES are blood vessels in the walls of the alveoli. 2  Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN. 3  While in the capillaries, blood gives off carbon dioxide through the capillary wall into the alveoli and takes up oxygen from air in the alveoli.ee what healthy lungs can do for you. Every cell in your body needs oxygen in order to live. The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried through your body.

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange Video For your lungs to perform their best, these airways need to be open during inhalation and exhalation and free from inflammation or swelling and excess or abnormal amounts of mucus. As the bronchial tubes pass through the lungs, they divide into smaller air passages called bronchioles.

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange Video Clearing the Air. The respiratory system has built-in methods to prevent harmful substances in the air from entering the lungs. Hairs in your nose help filter out large particles. Microscopic hairs, called cilia, are found along your air passages and move in a sweeping motion to keep the air passages clean.

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange Video Here, oxygen from the inhaled air passes through the alveoli walls and into the blood. After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale.

How Our Lungs Work: Main Processes & Function Let's review. Your lungs are a pair of organs found inside your chest. Their job is to bring oxygen in and get rid of carbon dioxide. Your cells need oxygen to work properly, and the only way to get it is by breathing in, or inhaling, air. Carbon dioxide is a waste product produced by your cells.

- Lung function tests, also called pulmonary (PULL-mun-ary) function tests, measure how well your lungs work. These tests are used to look for the cause of breathing problems, such as shortness of breath. Lung function tests measure: 1  How much air you can take into your lungs. 2  How much air you can blow out of your lungs and how fast you can do it. 3  How well your lungs deliver oxygen to your blood. 4  The strength of your breathing muscles.

Where are the lungs found? The lungs also help the body to get rid of CO 2 gas when we breathe out. There are a number of other jobs carried out by the lungs that include: 1  Changing the pH of blood (whether the blood is more acid or alkali) by increasing or decreasing the amount of CO 2 in the body. 2  Filtering out small blood clots formed in veins.

- Function: To deliver oxygen to and remove carbon dioxide from your blood. Network of airways. Your lungs are a pair of large sponge-like organs that almost fill your chest cavity. Your left lung is slightly smaller than your right lung, to make space for your heart. When you breathe in, you suck air in through your nose and mouth and down a tube called the trachea.

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange Video When you breathe in, the diaphragm contracts downward, creating a vacuum that causes a rush of fresh air into the lungs. The opposite occurs with exhalation, where the diaphragm relaxes upwards, pushing on the lungs, allowing them to deflate.

- The organs of your body that allow you to breathe are called your lungs. You have twoof them that work together, located in your chest inside the rib cage. The main purpose of your lungs is to breathe in good air and breathe out bad air.The good air contains oxygen, which your body needs.nside your lungs, oxygen is removed from the air you breathe and pumped into blood cells. Your lungs also get rid of harmful carbon dioxide from these cells. This process takes place inside hundreds of millions of tiny air sacs.Each adult lung is about the size of a football.

How Your Lungs Work This expansion lowers the pressure in the chest cavity below the outside air pressure. Air then flows in through the airways (from high pressure to low pressure) and inflates the lungs. When you exhale, the diaphragm and intercostal muscles relax and the chest cavity gets smaller.The decrease in volume of the cavity increases the pressure in the chest cavity above the outside air pressure. Air from the lungs (high pressure) then flows out of the airways to the outside air (low pressure).hen you exhale, the diaphragm and intercostal muscles relax and the chest cavity gets smaller. The decrease in volume of the cavity increases the pressure in the chest cavity above the outside air pressure.

What is the function of the respiratory system? The respiratory system is made up of airways (your nose, mouth, voice box, windpipe and bronchial tubes) and the lungs and the muscles and blood vessels connected to them.his is how the respiratory system works: First you breathe air in through your nose and mouth, which wet and warm the air so it won't irritate your lungs. Then the air travels through your voice box, down your windpipe and then though two bronchii (bronchial tubes) into your lungs.

Understand Your Lungs After your body uses the oxygen, it becomes carbon dioxide, which travels back to your lungs and is breathed out. Your lungs have a system, hair-like sweepers called cilia, to clean out the mucus. These cilia move mucus upwards, kind of like a conveyor belt. When smoke and other pollutants enter the lungs, the cilia are often paralyzed or destroyed. This causes airways to become swollen and narrowed.

Atelectasis What Are the Lungs? Your lungs are organs in your chest that allow your body to take in oxygen from the air. They also help remove carbon dioxide (a waste gas that can be toxic) from your body. The lungs' intake of oxygen and removal of carbon dioxide is called gas exchange. Gas exchange is part of breathing.
